How much is the hot air pressure of meltblown cloth?

The air source equipment is usually 70-90KPA, which is usually 0.07-0.09 kg. This is mainly determined by the pressure of the Roots blower or air compressor. According to Jingong ’s experience, most melt-blown cloth production lines are in the most In the best condition, the general optimal pressure of the die head is 60-75KPA.

Air source equipment: mainly to provide high-pressure air flow for the melt-blown cloth production line to blow out the molten polypropylene. Here, air source equipment with stable air volume and pressure is required. If the Roots blower pressure is generally within 98Kpa, it is generally 70 -80Kpa is enough, there is no need to investigate excessive pressure, different production lines need to be equipped with different air volume fans. Practice has proved that Roots blower is the most economical and stable melt jet source equipment. First, the pressure of the air compressor is too high, and the second is that oil lubrication is needed during the working process. Even if the air compressor that is called "oil-free" is only equipped with an oil-gas separator, there will still be a small amount of oil mist with the air flow. , Resulting in the smell of meltblown cloth, the smell of the mask is obvious, which leads to the failure of the detection. Judging from the situation of the 250 production lines supported by Jinquan Workers, more and more production lines are replacing air compressors with Roots blowers.
